System
   uname -a ==> OSF1 iam764 V5.1 2650 alpha
   Compiler: HP C++ V6.5-040
   Debugger: ladebug

How to Cause the Problem
   Connect from a desktop workstation (Linux Fedora Core 4) with ssh -Y
   Start ParaView 2.4 standalone
   Add a sphere
   Go to the animator
   Add a camera keyframe in the middle of the track
   Drag the keyframe to another time
   Crash occurs
